Yeah, i mean the press tool to push the calipers back in, makes it a lot easier then without.I'm not doing the rear ones, they are in good shape, the front ones are causing vibration when I brake, that's the main reason. If everything goes well I'll also later update the rear ones with Brembo.
I bought something like a press for the calipers to make it easier. I don't know the name in English.
I'll do the work at a DIY garage that rents the space with lift and tools, even proper space for paint jobs, really any kind of job that a garage can do. Here in Switzerland it's difficult to have the right space for that at home(and of course you have to follow a lot of rules if you live on a rental home)...there are a lot off mechanics around if I need advice, but I'm totally confident! I'll maybe ask them about the spark plugs.
Thanks for the advices 👍
And at a DIY shop you will be 100% fine, i do my brakes in front of my house/in the garage with a jack/axle stand, and did it without help the first time.
